Six parallel-plate capacitors of identical plate separation have different plate areas a, different capacitances c, and different dielectrics filling the space between the plates. below is a generic diagram of what each one of these capacitors might look like. (figure 1

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
